  • Vibratory device with repositionable weights and method of extending the useful life of vibratory devices
    Patent number: 9101959
    Abstract: A method comprises accessing a vibratory device having a rotor and first and second eccentric weights. The first weight is initially attached to the rotor's shaft in a manner such that its center of the mass is offset from the shaft in a first radial direction. The second weight is initially attached to the shaft in a manner such that its center of the mass is also offset in the first radial direction. The method further comprises reorienting the first and second weights relative to the shaft in a manner such that their centers of the mass are offset in a second radial direction. By performing these steps, the location of greatest bearing surface wear rate on the shaft is circumferentially relocated about the shaft. As such, the service life of an eccentric weight vibratory device is thereby extended.

  • Method of repositioning bearing wear in an industrial eccentric weight vibrator via power inversion and vibrator therefore
    Patent number: 9038491
    Abstract: A vibratory device comprises a rotor and an eccentric weight. The eccentric weight is mounted to the shaft and has a center of mass that is offset from the shaft axis. The vibratory device is configured such that the eccentric weight is in a first rotational orientation relative to the shaft and rotates with the shaft when the shaft rotates in a first direction about the shaft axis and such that the eccentric weight is in a second rotational orientation relative to the shaft when the shaft rotates in an opposite second direction about the shaft axis. The vibratory device is further configured such that the eccentric weight automatically transitions from the first rotational orientation to the second rotational orientation when the shaft is switched from rotating in the first direction to rotating in the second direction.
